Diaphragm Accumulators

 Diaphragm accumulators are compact and efficient energy storage devices used in hydraulic systems to maintain pressure, absorb shocks, and compensate for fluid volume changes. At Techknow Engineering Enterprise, we specialize in designing and supplying high-quality diaphragm accumulators that deliver reliable performance, safety, and durability in demanding industrial and mobile applications. Our accumulators are engineered to optimize hydraulic system efficiency while reducing wear, energy loss, and maintenance costs.

What Are Diaphragm Accumulators?

A diaphragm accumulator is a type of hydraulic accumulator that uses a flexible elastomeric diaphragm to separate the gas (usually nitrogen) and hydraulic fluid chambers. When the system pressure increases, hydraulic fluid enters the accumulator, compressing the nitrogen gas on the opposite side of the diaphragm. When system pressure drops, the compressed gas expands, forcing the stored fluid back into the hydraulic circuit. This ensures steady system pressure and smooth operation even under fluctuating loads.

Design and Construction

Techknow Engineering Enterprise manufactures diaphragm accumulators with robust construction to withstand high pressures and harsh working conditions. The accumulator body is typically made from carbon steel, stainless steel, or aluminum alloy, while the diaphragm is made from high-quality elastomer materials such as nitrile (NBR), hydrogenated nitrile (HNBR), or fluorocarbon (FKM), depending on the fluid type and temperature range.

Key features include:

• Compact and lightweight design for space-saving installations.

• Pre-charged nitrogen gas chamber for reliable pressure response.

• Threaded or flanged connections for easy integration into hydraulic systems.

• Replaceable diaphragm options for extended service life.

• Corrosion-resistant coatings for enhanced durability.

Functions of Diaphragm Accumulators

Diaphragm accumulators perform several critical functions within hydraulic systems:

1. Energy Storage: Stores hydraulic energy and releases it when the pump output is insufficient.

2. Pressure Stabilization: Maintains consistent system pressure during varying loads.

3. Shock Absorption: Dampens hydraulic shocks and pulsations caused by pumps or directional valves.

4. Leakage Compensation: Automatically compensates for small fluid leaks or temperature-related volume changes.

5. Emergency Power Supply: Provides backup hydraulic pressure in case of pump failure.

Applications

Techknow diaphragm accumulators are widely used in numerous industries and systems, including:

• Mobile hydraulics – tractors, excavators, and cranes.

• Industrial machinery – hydraulic presses, machine tools, and injection molding machines.

• Energy and power plants – lubrication and control systems.

• Marine and offshore systems – stabilization and steering hydraulics.

• Automotive and aerospace sectors – brake and suspension systems.
